The inequalities in the level of this shore line at different 

 points, it will be seen, range from 138 to 249 feet above mean 

 tide. It is highest upon ihe crystalline rocks and lowest upon 

 the unaltered carboniferous sediments. The problem as to the 

 cause or causes of these imequal altitudes is a very comjjlex one, 

 and is not yet clearly understood. Iriome geologists suppose the 

 post-glacial uplift of the coast l)t)rder to have been unequal in 

 dih'erent parts, others agairj hold that though the uplift may 

 have been equal throughout m a certain area, say within the 

 province, that there was unequal subsidence since which has 

 produced deformation. It is not improbable that both may be 

 partly right, that is, if we consider only the movements of the 

 land. But we have also to take into account thf possible move- 

 ments of the ocean, or hydrosphere, wliether or not it has under- 

 gone secular changes of level with reference to the earth's centre. 

 Notwithstanding the view held by most people, even by geolo- 

 gists, that the sea level is constant, in other words, that the 

 earth's radius in oceanic areas is always the same length, we 

 must admit that if ihe level of the land changes in those parts 

 adjacent to the sea shore, the ground beneath the ocean, at least 

 in the coastal zone, must likewise be subject to the same change 

 of level. Lyell says, 'Tn every country the land is, in some
